Preoperative airway assessment and anticipation of a difficult airway is of utmost critical value in anaesthesiology as failure to secure airway can lead to morbidity and mortality. The study evaluated ratio of height-to-thyromental distance (RHTMD) and ratio of height-to-sternomental distance (RHSMD) as predictors of a difficult airway.
The prospective observational study evaluated 131 adult participants scheduled for elective surgery under general anaesthesia. In addition to the preoperative airway assessment, RHTMD and RHSMD were calculated. https://www.selleckchem.com/products/dt-061-smap.html Correlation of these ratios with the Cormack-Lehane grading of glottis visualisation on direct laryngoscopic view following induction of anaesthesia was analyzed. The optimal cut-off point for RHTMD and RHSMD were identified using receiver operating characteristic curve analysis.
The incidence of difficult intubation was 14.50%. The cut-off values for RHTMD and RHSMD were ＜ 21.50 (sensitivity 85.25%, specificity 100.00%) and ＜ 10.50 (sensitivity 84.21%, specificity 96.42%) respectively for predicting difficult airway. The area under the curve with 95% confidence interval for RHTMD was 0.875 (0.730-1.000) and that for RHSMD was 0.890 (0.777-1.000).
RHTMD was found to be a better predictor of difficult intubation and restricted laryngoscopic view compared to RHSMD.

This study was conducted to evaluate the risk factors for postoperative complications and their effects on hospital stay in geriatric surgical patients (aged ? 80 years).
A total of 404 geriatric patients (aged ? 80 years) who underwent noncardiac surgery were enrolled in this study. Their preoperative, perioperative, and postoperative data were collected and subjected to univariate and multivariate analyses to calculate the odds ratio of risk factors. The risk of discharge was analyzed by calculating the hazard ratio to evaluate their relationship with postoperative complications.
Approximately three-fourths (76.0%) of the patients had hypertension preoperatively, and 5.9% of them developed at least one postoperative complication. Respiratory disorders were the most frequent postoperative complications. Multivariate analysis revealed emergency surgery, preoperative renal diseacertain conditions need more attention to prevent the development of different types of postoperative complications. Those who did develop postoperative respiratory complications, postoperative neurological complications, and infection might require prolonged hospitalization. Physicians must pay more attention preoperatively to the risk factors that increase postoperative complications.Particle therapy is a promising and evolving modality of radiotherapy that can be used to treat tumors that are radioresistant to conventional photon beam radiotherapy. It has unique biological and physical advantages compared with conventional radiotherapy. The characteristic feature of particle therapy is the "Bragg peak," a steep and localized peak of dose, that enables precise delivery of the radiation dose to the tumor while effectively sparing normal organs. Especially, the charged particles (e.g., proton, helium, carbon) cause a high rate of energy loss along the track, thereby leading to high biological effectiveness, which makes particle therapy attractive. Using this property, the particle beam induces more severe DNA double-strand breaks than the photon beam, which is less influenced by the oxygen level. This review describes the general biological and physical aspects of particle therapy for oncologists, including non-radiation oncologists and beginners in the field.Cushing syndrome is the result of excessive levels of glucocorticoids. Endogenous Cushing syndrome is rare with an incidence of two to three cases per million per year. Clinically, the presentation consists of a characteristic phenotype including skin symptoms and metabolic manifestations. A frequent co-morbidity with high impact on quality of life is Cushing syndrome associated myopathy. It characteristically affects the proximal myopathy, impairing stair climbing and straightening up. The pathophysiology is complex and involves protein degradation via the forkhead box O3 (FOXO3) pathway, intramuscular fat accumulation, and inactivity-associated muscle atrophy. Surgical remission of Cushing syndrome is the most important step for recovery of muscle function. Restoration depends on age, co-morbidities and postoperative insulin-like growth factor concentrations. At average, functionality remains impaired during the long-term compared to age and sex matched control persons. Growth hormone therapy in individuals with impaired growth hormone secretion could be an option but has not been proved in a randomized trial.The survival benefit of neoadjuvant chemotherapy (NAC) prior to surgical resection in colorectal cancer with liver metastases (CRCLM) patients remains controversial. The aim of this study was to compare overall outcome of CRCLM patients who underwent NAC followed by surgical resection versus surgical treatment first.
We retrospectively analyzed 429 patients with stage IV colorectal cancer with synchronous liver metastases who underwent simultaneous liver resection between January 2008 and December 2016. Using propensity score matching, overall outcome between 60 patients who underwent NAC before surgical treatment and 60 patients who underwent surgical treatment first was compared.
Before propensity score matching, metastatic cancer tended to involve a larger number of liver segments and the primary tumor size was bigger in the NAC group than in the primary resection group, so that a larger percentage of patients in the NAC group underwent major hepatectomy (P&lt;0.001). After propensity score matching, demographic features and pathologic outcomes showed no significant differences between the 2 groups. In addition, there was no significant difference in short-term recovery outcomes such as postoperative morbidity (P=0.603) and oncologic outcome, including 3-year overall survival rate (P=0.285) and disease-free survival rate (P=0.730), between the 2 groups.
NAC prior to surgical treatment in CRCLM is considered a safe treatment that does not increase postoperative morbidity, and its impact on oncologic outcome was not inferior.
